I have just set up the compu dobby on my new to me AVL 16 shaft Production dobby loom. When the solenoid check is going though its sequence when the compu dobby is turned on shaft 3 finger (don't know what else to call it) pulls in slightly and gets stuck down when the solenoid check comes to it. I am in Australia so cannot visit or call AVL but will email them following this post. Can anyone help/suggest what I can do to amend the problem? It is a Compu dobby 1. Thanks in anticipation of replies.
